Frequency converters from visible to mid-infrared with periodically poled RbTiOPO4

Electric-field poling has been used to fabricate quasi-phase-matched frequency converters in RbTiOPO4. A more accurate Sellmeier equation has been obtained for wavelengths between 0.43 and 3.4 μm. The dispersion of the thermo-optic coefficient for nz refractive index has been derived in the near- to...

Zusammenfassung:Electric-field poling has been used to fabricate quasi-phase-matched frequency converters in RbTiOPO4. A more accurate Sellmeier equation has been obtained for wavelengths between 0.43 and 3.4 μm. The dispersion of the thermo-optic coefficient for nz refractive index has been derived in the near- to mid-infrared spectral region. The nonlinear performance of periodically poled RbTiOPO4 obtained in the infrared optical parametric devices is comparable to that of periodically poled KTiOPO4.
